Vibrational spectra of crystalline halomercurate(II) complexes

Abstract: The v~brational spectra of crystalline halomercurate salts with anionic stoicheiometries HgX3-, HgX42-, Hg2X6-, HgsXs2-(where X = C1, Br, I) have been studied. The cations Me&+, Et4N+, Ph&+, and pyH+ were used as necessary. The effect of crystalline symmetry and packing on the spectra of both anion and cation are discussed and the spectra are used to deduce the most probable crystalline packmg for salts contamng the HgzXs-and Hg3Xs2-specles. The spectra of the cations 3Ie&S+ and Et4S+ are assigned and d~scusse… Show more

“…expected for a [Hgl3]-ion of any shape, but is in accordance with predictions for a D2h dimeric anion [Hg2Ie] 2_ which, based on tetrahedral geometry around the metal, should show four IR-active (BIU + B2U + 2B3U) modes [18]. The possibility of the [Hgale] 2 -system being a mixture can be ruled out on the ground that this does not show bands at the same wavenumbers as [HgL*] 2- [4] and HgI2-2L [19].…”

“…Very few preparative and spectroscopic studies have been made on iodomercurate(II) complexes with dimeric or polymeric anionic structures [3][4][5][6]. It was pointed out by Deacon [7] that no cation appears to give both [Hg2ls] _ and [Hgsls] 2-complex anions.…”
